What It Is

This is an OEM 5-inch deck wheel kit (part number M111489) designed to replace the front or side gauge wheels on select John Deere lawn tractors. It keeps the mower deck level and prevents scalping on uneven terrain.

Fitment & Compatibility

Before buying, verify your model matches John Deere STX38, STX46, LX172, LX173, LX176, LX178, LX240, GS25, LT133, LT150, LT160, LT166, LT170, GT225, or GT235. Also check that your deck is 38 or 46 inches—larger decks may require different wheel sizes. This is an OEM part, so it’s a direct bolt-on for listed models. Measure your current wheel’s outside diameter (should be 5 inches) and the bolt hole spacing (typically 3.5 inches center-to-center) to confirm compatibility. The kit includes the wheel, tire, and hardware.

Key Things to Know

• Quality: OEM construction with durable rubber tire and metal hub—holds up better than aftermarket plastic alternatives.
• Installation: Simple swap; remove the old wheel and axle bolt, then install the new wheel with included hardware. No special tools needed.
• Common Gotcha: The axle bolt can be rusted or seized on older mowers. Use penetrating oil beforehand to avoid stripping.
• Fit Note: Not compatible with newer John Deere models using stamped steel decks (e.g., D100 series) or zero-turn mowers.

Should You Buy It

If you own one of the listed John Deere tractors and need a direct-fit, long-lasting replacement for a worn or damaged deck wheel, this OEM kit is a reliable choice. It’s slightly pricier than generic options, but the fit and durability justify the cost for frequent mowing.
